Termite mound architecture regulates nest temperature and correlates with species identities of symbiotic fungi
Autor: Risto Vesala, Anni Harjuntausta, Anu Hakkarainen, Petri Rönnholm, Petri Pellikka, Jouko Rikkinen
Publikováno v: PeerJ, Vol 6, p e6237 (2019)
Background Large and complex mounds built by termites of the genus Macrotermes characterize many dry African landscapes, including the savannas, bushlands, and dry forests of the Tsavo Ecosystem in southern Kenya. The termites live in obligate symbio

Assessing CO2 and CH4 fluxes from mounds of African fungus-growing termites
Autor: Matti Räsänen, Risto Vesala, Petri Rönnholm, Laura Arppe, Petra Manninen, Markus Jylhä, Jouko Rikkinen, Petri Pellikka, Janne Rinne
Termites play an essential role in decomposing dead plant material in tropical ecosystems and are thus major sources of gaseous C emissions in many environments. In African savannas, fungus-growing termites are among the ecologically most influential

Plant-fungal feedbacks of nitrogen deposition to peatland carbon sink potential
Autor: Tuula Larmola, Sylwia Adamczyk, Heikki Kiheri, Risto Vesala, Petra Straková, Jill Bubier, Netty van Dijk, Nancy Dise, Hannu Fritze, Sari Juutinen, Raija Laiho, Tim Moore, Mats Nilsson, Taina Pennanen
We examined how changes in plant-fungal relationships induced by atmospheric nitrogen (N) deposition alter nutrient limitation and carbon sequestration in two main types of peatlands, bogs and fens. The study was carried out at three of the longest r

You eat what you find - Local patterns in vegetation structure control diets of African fungus-growing termites
Autor: Risto Vesala, Aleksi Rikkinen, Petri Pellikka, Jouko Rikkinen, Laura Arppe
Fungus-growing termites and their symbiotic Termitomyces fungi are critically important carbon and nutrient recyclers in arid and semiarid environments of sub-Saharan Africa. A major proportion of plant litter produced in these ecosystems is decompos

Atmospheric nitrogen enrichment changes nutrient stoichiometry and reduces fungal N supply to peatland ericoid mycorrhizal shrubs
Autor: Nancy B. Dise, Risto Vesala, Erik A. Hobbie, Netty van Dijk, Heikki Kiheri, Tuula Larmola
Peatlands store one third of global soil carbon (C) and up to 15% of global soil nitrogen (N) but often have low plant nutrient availability owing to slow organic matter decomposition under acidic and waterlogged conditions. In rainwater-fed ombrotro

Caste-specific nutritional differences define carbon and nitrogen fluxes within symbiotic food webs in African termite mounds
Autor: Jouko Rikkinen, Risto Vesala, Laura Arppe
Publikováno v: Scientific Reports, Vol 9, Iss 1, Pp 1-11 (2019)
Scientific Reports
Fungus-growing termites of the genus Macrotermes cultivate symbiotic fungi (Termitomyces) in their underground nest chambers to degrade plant matter collected from the environment. Although the general mechanism of food processing is relatively well-

Diversity of fungus-growing termites (Macrotermes) and their fungal symbionts (Termitomyces) in the semiarid Tsavo Ecosystem, Kenya
Autor: Jouko Rikkinen, Petri Pellikka, Kare Liimatainen, Tuula Niskanen, Risto Vesala, Hamadi Boga
Fungus-growing termites of the subfamily Macrotermitinae together with their highly specialized fungal symbionts (Termitomyces) are primary decomposers of dead plant matter in many African savanna ecosystems. The termites provide crucial ecosystem se

The community of needle endophytes reflects the current physiological state of Norway spruce
Autor: Taina Pennanen, Sannakajsa Velmala, Tiina Rajala, Risto Vesala, Aino Smolander
Publikováno v: Fungal Biology. 118:309-315
This study investigated fungal endophytes in the needles of Norway spruce (Picea abies) cuttings in relation to host tree growth. We also determined the prevalence of endophytes in needles incubated for six months. The cuttings originated from clonal
